Subconjunctival bleeding, also known as subconjunctival hemorrhage or subconjunctival haemorrhage, is bleeding from a small blood vessel over the whites of the eye. It results in a red spot in the white of the eye. [1] There is generally little to no pain and vision is not affected. [2] [3] Generally only one eye is affected. [2]
A subconjunctival hemorrhage appears as a bright red patch on the white of the eye and is commonly referred to as a burst blood vessel. In hyphema, blood pools in the anterior chamber, where the iris (the colored part of the eye) and the pupil are located. Hyphemas are graded based on the amount of blood covering the cornea.
